The surge counter includes Test and Reset buttons on the

touchpad display. Pressing Test adds one count. Pressing

Reset clears the counter’s memory and sets the display to zero.

The counter includes a SuperCap charge device to store

the surge count in the event of a power loss. The SuperCap

requires no maintenance giving it an advantage over

replaceable batteries.

Phase A, B & C: Green LED indicators—one per phase. Green is

good. Out indicates problem. Every suppression element in this SPD

is monitored. (N-G indicates on Phase A)

Service LED (Red): LED illuminates in the event of problems. This

indicator is logic-connected to the Phase LEDs. Should a Phase

LED go out the Service LED will illuminate and the Audible Alarm

will sound.

Test: Tests red Service LED and Audible Alarm, and changes state

of Dry Contacts.

Alarm Silence: Turns Audible Alarm off. (Alarm is deactivated when

the Silence LED is illuminated.)

Surge Counter Count: (if equipped) Increments optional surge

counter by one. (+1)

Surge Counter Reset: (if equipped) Resets optional surge counter

to zero. (0)

Dry Contact Option

Two sets of Form C dry contacts are included with the Dry

Contact option. Dry Contacts change state during inoperative

conditions, including loss of power. Any status change can

be monitored elsewhere via Dry Contacts.

A Terminal Block includes two sets of Normally Open (N.O.)

and Normally Closed (N.C) contacts. Both sets of contacts

operate the same. This is shown in Figure 5.

A typical application using a Normally Closed conguration

would connect to one set of the N.C. and Common terminals.

During an inoperative condition, the SPD’s dry contact would

change state from normally closed to open. We generally

suggest the Normally Closed conguration because it will

detect a wiring defect, such as cut wire(s), where N.O. will not.

Please note: Dry Contacts are designed for low voltage or

control signals only.

Maximum switching current is 5A

Maximum switching voltage is 240V DC or AC.

Higher energy applications require additional relay

implementation outside the TVSS.

An optional Remote Monitor accessory is available to provide

visual and audible status. The Remote Monitor will consume

one of the two sets of Dry Contacts.

Remote Monitor Accessory Option

A Remote Monitor is available for remote annunciation.

It requires a standalone 120V power source (wall plug

transformer) and uses one set of Form C dry contacts. The

Remote Monitor can be congured to monitor several APT

SPDs simultaneously. Installation is detailed in a separate

document. Contact factory as appropriate.
